HTTP Strict Transport Security (HSTS) is a security mechanism that protects secure HTTPS websites against attacks. It allows servers to declare that web browsers should always connect to your website using HTTPS, instead of making insecure connections via HTTP. HSTS provides an additional layer of security around SSL-only websites by instructing browsers to remember that connections to your website should always use SSL.
